Indivior Announces Inclusion in the U.S. Russell 2000® and 3000® Indexes

Richmond, VA, June 30, 2025 - Indivior PLC (Nasdaq / LSE: INDV) will be added as a member of the U.S. small-cap Russell 2000® Index, effective after the U.S. market opens today as part of the 2025 Russell indexes reconstitution. The annual reconstitution of the Russell U.S. indexes captures the 4,000 largest U.S. stocks as of April 30, ranking them by total market capitalization. Membership in the Russell 2000® Index, which remains in place for one year, is based on membership in the broad-market Russell 3000® Index. The stock also was automatically added to the appropriate growth and value indexes.

"Indivior's inclusion in the U.S. Russell indexes further aligns our capital markets presence with our growing U.S. business profile. In 2024, 85% of our net revenue was generated in the U.S. predominately from SUBLOCADE®, our first-in-class, long-acting injectable medication for the treatment of opioid use disorder. We are committed to building our U.S. presence and increasing value for our stakeholders," said Joe Ciaffoni, Chief Executive Officer of Indivior.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. According to data as of the end of June 2024, about $10.6 trillion in assets are benchmarked against the U.S. Russell indexes, which belong to FTSE Russell, the global index provider.
